Wrist arthroscopy is a standard procedure in hand surgery for diagnosis and treatment of wrist injuries. Even though not generally recommended for similar procedures, general administration of perioperative antibiotic prophylaxis (PAP) is still widely used in wrist arthroscopy. A clinical ambispective dual-centre study was performed to determine whether PAP reduces postoperative infection rates after soft tissue-only wrist arthroscopies. Retrospective and prospective data was collected at two hospitals with departments specialized in hand surgery. During the study period, 464 wrist arthroscopies were performed, of these 178 soft-tissue-only interventions met the study criteria and were included. Signs of postoperative infection and possible adverse drug effects (ADEs) of PAP were monitored. Additionally, risk factors for surgical site infection (SSIs), such as diabetes mellitus and BMI, were obtained.Aims
Methods
The underlying natural history of suspected scaphoid fractures (SSFs) is unclear and assumed poor. There is an urgent requirement to develop the literature around SSFs to quantify the actual prevalence of intervention following SSF. Defining the risk of intervention following SSF may influence the need for widespread surveillance and screening of SSF injuries, and could influence medicolegal actions around missed scaphoid fractures. Data on SSF were retrospectively gathered from virtual fracture clinics (VFCs) across a large Scottish Health Board over a four-year period, from 1 January 2018 to 31 December 2021. The Bluespier Electronic Patient Record System identified any surgical procedure being undertaken in relation to a scaphoid injury over the same time period. Isolating patients who underwent surgical intervention for SSF was performed by cross-referencing the unique patient Community Health Index number for patients who underwent these scaphoid procedures with those seen at VFCs for SSF over this four-year period.Aims

There is ambiguity surrounding the degree of scaphoid union required to safely allow mobilization following scaphoid waist fracture. Premature mobilization could lead to refracture, but late mobilization may cause stiffness and delay return to normal function. This study aims to explore the risk of refracture at different stages of scaphoid waist fracture union in three common fracture patterns, using a novel finite element method. The most common anatomical variant of the scaphoid was modelled from a CT scan of a healthy hand and wrist using 3D Slicer freeware. This model was uploaded into COMSOL Multiphysics software to enable the application of physiological enhancements. Three common waist fracture patterns were produced following the Russe classification. Each fracture had differing stages of healing, ranging from 10% to 90% partial union, with increments of 10% union assessed. A physiological force of 100 N acting on the distal pole was applied, with the risk of refracture assessed using the Von Mises stress.Aims
Methods
The primary aim of this study was to report the radiological outcomes of patients with a dorsally displaced distal radius fracture who were randomized to a moulded cast or surgical fixation with wires following manipulation and closed reduction of their fracture. The secondary aim was to correlate radiological outcomes with patient-reported outcome measures (PROMs) in the year following injury. Participants were recruited as part of DRAFFT2, a UK multicentre clinical trial. Participants were aged 16 years or over with a dorsally displaced distal radius fracture, and were eligible for the trial if they needed a manipulation of their fracture, as recommended by their treating surgeon. Participants were randomly allocated on a 1:1 ratio to moulded cast or Kirschner wires after manipulation of the fracture in the operating theatre. Standard posteroanterior and lateral radiographs were performed in the radiology department of participating centres at the time of the patient’s initial assessment in the emergency department and six weeks postoperatively. Intraoperative fluoroscopic images taken at the time of fracture reduction were also assessed.Aims
Methods
To explore individuals’ experience of a scaphoid waist fracture and its subsequent treatment. A purposive sample was created, consisting of 49 participants in the Scaphoid Waist Internal Fixation for Fractures Trial of initial surgery compared with plaster cast treatment for fractures of the scaphoid waist. The majority of participants were male (35/49) and more younger participants (28/49 aged under 30 years) were included. Participants were interviewed six weeks or 52 weeks post-recruitment to the trial, or at both timepoints. Interviews were semistructured and analyzed inductively to generate cross-cutting themes that typify experience of the injury and views upon the treatment options.Aims
Methods
To estimate the potential cost-effectiveness of adalimumab compared with standard care alone for the treatment of early-stage Dupuytren’s disease (DD) and the value of further research from an NHS perspective. We used data from the Repurposing anti-TNF for Dupuytren’s disease (RIDD) randomized controlled trial of intranodular adalimumab injections in patients with early-stage progressive DD. RIDD found that intranodular adalimumab injections reduced nodule hardness and size in patients with early-stage DD, indicating the potential to control disease progression. A within-trial cost-utility analysis compared four adalimumab injections with no further treatment against standard care alone, taking a 12-month time horizon and using prospective data on EuroQol five-dimension five-level questionnaire (EQ-5D-5L) and resource use from the RIDD trial. We also developed a patient-level simulation model similar to a Markov model to extrapolate trial outcomes over a lifetime using data from the RIDD trial and a literature review. This also evaluated repeated courses of adalimumab each time the nodule reactivated (every three years) in patients who initially responded.Aims
Methods
The aim of this study was to develop a core outcome set of what to measure in all future clinical research on hand fractures and joint injuries in adults. Phase 1 consisted of steps to identify potential outcome domains through systematic review of published studies, and exploration of the patient perspective through qualitative research, consisting of 25 semi-structured interviews and five focus groups. Phase 2 involved key stakeholder groups (patients, hand surgeons, and hand therapists) prioritizing the outcome domains via a three-round international Delphi survey, with a final consensus meeting to agree the final core outcome set.Aims
Methods
Dupuytren’s contracture is characterized by increased fibrosis of the palmar aponeurosis, with eventual replacement of the surrounding fatty tissue with palmar fascial fibromatosis. We hypothesized that adipocytokines produced by adipose tissue in contact with the palmar aponeurosis might promote fibrosis of the palmar aponeurosis. We compared the expression of the adipocytokines adiponectin and leptin in the adipose tissue surrounding the palmar aponeurosis of male patients with Dupuytren’s contracture, and of male patients with carpal tunnel syndrome (CTS) as the control group. We also examined the effects of adiponectin on fibrosis-related genes and proteins expressed by fibroblasts in the palmar aponeurosis of patients with Dupuytren’s contracture.Aims
Methods
The evidence demonstrating the superiority of early MRI has led to increased use of MRI in clinical pathways for acute wrist trauma. The aim of this study was to describe the radiological characteristics and the inter-observer reliability of a new MRI based classification system for scaphoid injuries in a consecutive series of patients. We identified 80 consecutive patients with acute scaphoid injuries at one centre who had presented within four weeks of injury. The radiographs and MRI scans were assessed by four observers, two radiologists, and two hand surgeons, using both pre-existing classifications and a new MRI based classification tool, the Oxford Scaphoid MRI Assessment Rating Tool (OxSMART). The OxSMART was used to categorize scaphoid injuries into three grades: contusion (grade 1); unicortical fracture (grade 2); and complete bicortical fracture (grade 3).Aims

The primary aim of this study was to describe long-term patient-reported outcomes after ulna shortening osteotomy for ulna impaction syndrome. Overall, 89 patients treated between July 2011 and November 2017 who had previously taken part in a routine outcome evaluation up to 12 months postoperatively were sent an additional questionnaire in February 2021. The primary outcome was the Patient-Rated Wrist and Hand Evaluation (PRWHE) total score. Secondary outcomes included patient satisfaction with treatment results, complications, and subsequent treatment for ulnar-sided wrist pain. Linear mixed models were used to compare preoperative, 12 months, and late follow-up (ranging from four to nine years) PRWHE scores.Aims

Osteoarthritis (OA) affecting the thumb carpometacarpal joint (CMCJ) is a common painful condition. In this study, we aimed to explore clinicians’ approach to management with a particular focus on the role of specific interventions that will inform the design of future clinical trials. We interviewed a purposive sample of 24 clinicians, consisting of 12 surgeons and 12 therapists (four occupational therapists and eight physiotherapists) who managed patients with CMCJ OA. This is a qualitative study using semi-structured, online interviews. Interviews were audio-recorded, transcribed verbatim, and analyzed using thematic analysis.Aims
Methods
Low-energy distal radius fractures (DRFs) are the most common upper arm fractures correlated with bone fragility. Vitamin D deficiency is an important risk factor associated with DRFs. However, the relationship between DRF severity and vitamin D deficiency is not elucidated. Therefore, this study aimed to identify the correlation between DRF severity and serum 25-hydroxyvitamin-D level, which is an indicator of vitamin D deficiency. This multicentre retrospective observational study enrolled 122 female patients aged over 45 years with DRFs with extension deformity. DRF severity was assessed by three independent examiners using 3D CT. Moreover, it was categorized based on the AO classification, and the degree of articular and volar cortex comminution was evaluated. Articular comminution was defined as an articular fragment involving three or more fragments, and volar cortex comminution as a fracture in the volar cortex of the distal fragment. Serum 25-hydroxyvitamin-D level, bone metabolic markers, and bone mineral density (BMD) at the lumbar spine, hip, and wrist were evaluated six months after injury. According to DRF severity, serum 25-hydroxyvitamin-D level, parameters correlated with bone metabolism, and BMD was compared.Aims

Current National Institute for Health and Clinical Excellence (NICE) guidance advises that MRI direct from the emergency department (ED) should be considered for suspected scaphoid fractures. This study reports the current management of suspected scaphoid fractures in the UK and assesses adherence with NICE guidance. This national cross-sectional study was carried out at 87 NHS centres in the UK involving 122 EDs and 184 minor injuries units (MIUs). The primary outcome was availability of MRI imaging direct from the ED. We also report the specifics of patient management pathways for suspected scaphoid fractures in EDs, MIUs, and orthopaedic services. Overall, 62 of 87 centres (71%) had a guideline for the management of suspected scaphoid fractures.Aims
Methods
Studies on long-term patient-reported outcomes after open surgery for triangular fibrocartilage complex (TFCC) are scarce. Surgeons and patients would benefit from self-reported outcome data on pain, function, complications, and satisfaction after this surgery to enhance shared decision-making. The aim of this study is to determine the long-term outcome of adults who had open surgery for the TFCC. A prospective cohort study that included patients with open surgery for the TFCC between December 2011 and September 2015. In September 2020, we sent these patients an additional follow-up questionnaire, including the Patient-Rated Wrist Evaluation (PRWE), to score satisfaction, complications, pain, and function.Aims
Methods
To determine the role of early MRI in the management of suspected scaphoid fractures. A total of 337 consecutive patients presenting to an emergency department (ED) following wrist trauma over a 12-month period were prospectively included in this service evaluation project. MRI was not required in 62 patients with clear diagnoses, and 17 patients were not managed as per pathway, leaving a total of 258 patients with normal scaphoid series radiographs who were then referred directly from ED for an acute wrist MRI scan. Patient demographics, clinical details, outcomes, and complications were recorded at a minimum of a year following injury.Aims
Methods
Displaced distal radius fractures were investigated at a level 1 major trauma centre during the COVID-19 2020 lockdown due to the implementation of temporary changes in practice. The primary aim was to establish if follow-up at one week in place of the 72-hour British Orthopaedic Association Standards for Trauma & Orthopaedics (BOAST) guidance was safe following manipulation under anaesthetic. A parallel adaptation during lockdown was the non-expectation of Bier’s block. The secondary aim was to compare clinical outcomes with respect to block type. Overall, 90 patients were assessed in a cross-sectional cohort study using a mixed, retrospective-prospective approach. Consecutive sampling of 30 patients pre-lockdown (P1), 30 during lockdown (P2), and 30 during post-lockdown (P3) was applied. Type of block, operative status, follow-up, and complications were extracted. Primary endpoints were early complications (≤ one week). Secondary endpoints were later complications including malunion, delayed union or osteotomy.Aims
Methods
Acute distal biceps tendon repair reduces fatigue-related pain and minimises loss of forearm supination and elbow flexion strength. We report the short- and long-term outcome following repair using an EndoButton technique. Between 2010 – 2018, 102 patients (101 males; mean age 43 years) underwent acute (□6 weeks) distal biceps tendon repair using an EndoButton technique. The primary short-term outcome was complications. The primary long-term outcome was the Quick-DASH (Q-DASH). Secondary outcomes included the Oxford Elbow Score (OES), EuroQol-5D-3L (EQ-5D), return to function and satisfaction. At mean short-term follow-up of 4 months (2.0 – 55.5) eight patients (7.8%) experienced a major complication and 34 patients (33.3%) experienced a minor complication. Major complications included re-rupture (n=3, 2.9%), unrecovered nerve injury (n=4, 3.9%) and surgery for heterotopic ossification excision (n=1, 1.0%). Three patients (2.9%) required surgery for a complication. Minor complications included neuropraxia (n=27, 26.5%) and superficial infection (n=7, 6.9%). At mean follow-up of 5 years (1 – 9.8) outcomes were collected from 86 patients (84.3%). The median Q-DASH, OES, EQ-5D and satisfaction scores were 1.2 (IQR 0 – 5.1), 48 (IQR, 46 – 48), 0.80 (IQR, 0.72 – 1.0) and 100/100 (IQR, 90 – 100) respectively. Most patients returned to sport (82.3%) and employment (97.6%) following surgery. Unrecovered nerve injury was associated with a poor outcome according to the Q-DASH (p< 0.001), although re-rupture and further surgery were not (p > 0.05). Acute distal biceps tendon repair using an EndoButton technique results in excellent patient reported outcomes and health-related quality of life. Although rare, unrecovered nerve injury adversely affects outcome.
The aim of this study was to identify the effect of COVID-19 lockdown on the rates, types, mechanisms and mortality of musculoskeletal trauma across Scotland. Data for all musculoskeletal trauma requiring operative treatment was collected prospectively from five orthopaedic units across Scotland during the initial lockdown period (23/03/2020-28/05/2020). This was compared with data for the same timeframe in 2018 and 2019. Data collected included all cases requiring surgery, injury type, mechanism of injury, and inpatient mortality. 1315 patients received operative treatment in 2020 compared to 1791 in 2019 and 1719 in 2018. The numbers of all injury types decreased, but the relative frequency of hip fractures increased(36.3% 2020 vs 30.2% 2019, p<0.0001 & 30.7% 2018, p<0.0001). Significant increases were seen in proportion of DIY-related injuries(3.1% 2020 vs 1.7% 2019, p=0.01 & 1.6% 2018, p<0.01) and injuries caused by falls(65.6% 2020 vs 62.6% 2019, p=0.08 & 61.9% 2018, p=0.05). Significant decreases were seen in proportion of RTCs(2.6% 2020 vs 5.4% 2019, p<0.0001 & 4.2% 2018, p=0.02) and occupational injuries(1.8% 2020 vs 3.0% 2019, p=0.03 & 2.3% 2018, p=0.01). A significant increase in proportion of self-harm injuries was seen(1.7% 2020 vs 1.1% 2019, p=0.19 & 0.5% 2018, p<0.0001). Mortality of trauma patients was significantly higher in 2020 (4.9%), than in 2019 (3.2%, p=0.02) and 2018 (2.6%, p<0.0001). In conclusion, lockdown has resulted in a marked reduction of musculoskeletal trauma requiring surgery in Scotland. There have been major changes in types and mechanisms of injury, and mortality of trauma patients has risen significantly.
Tranexamic acid (TXA) is an inexpensive antifibrinolytic. Currently there are no national guidelines in the UK that promote the use of TXA in femoral fragility fracture (FFF) management. The aim of the study was to determine whether intra-operative intravenous TXA affects the requirement for post-operative blood transfusion following FFF surgery. A prospective non-randomized case-control study of consecutive FFF admitted to the study centre was performed. 361 patients were included in the study (mean age 81.4yrs; mean BMI 23.5; 73.7% female). TXA was given at the discretion of the operating surgeon, with 178 (49%) patients receiving TXA. Patient demographics, surgical management, peri-operative haemoglobin (Hb) and haematocrit, intravenous TXA use, and requirement for blood transfusion were recorded prospectively. Percentage fall in Hb from preoperative level was calculated at postoperative day one. Calculated-blood-loss (CBL) was determined using the Nadler and Gross formulae. The groups were well matched in terms of patient demographics, injury types and surgical management. The requirement for postoperative blood transfusion was significantly reduced in the TXA group: 15/178 (8.4%) compared to 58/183 (31.7%) (p<0.001; Chi square). TXA significantly reduced both the percentage fall in Hb (mean difference 4.3%, p<0.001) and the CBL (mean difference -222ml, p<0.001). There was no difference in venous thrombosis embolism events between the groups. Intra-operative intravenous TXA during the surgical management of FFF significantly reduced rate of transfusion, CBL and the percentage drop in HB.
Gavril Ilizarov advocated a fine wire tension of between 900N and 1200N for circular frame construction. Wire tension can be achieved via a tensioning device or ‘Russian tensioning’ (a fixed wire lengthening around a bolt). There is limited information on the latter technique. This study explored the tensions achieved via Russian tensioning and reports the impact of a second wire on construct tension. A single 160mm stainless-steel ring was constructed, then 1.8mm stainless steel wires were secured using a Russian fixation bolt and Russian tensioned with a 2nd bolt. The angle subtended by tensioning using the 2nd bolt was measured using a goniometer. Angles of 45°, 70° and 90° were repeated in triplicates, with wire tension measured using a calibrated tensiometer. A second, orthogonal wire was added and tensioned to the same angle. Tensions of both wires were remeasured and recorded. Unpaired t-tests were used to compare mean tensions. A value of p<0.05 was considered significant. Tensioning at all angles was insufficient to achieve the target range of 900–1200N (range 99–110N). A second, orthogonal wire changed frame dynamics such that a 90° angle resulted in both wires achieving adequate tension (mean 1143N, SD 307N). Increases were significant across all tensioning angles (p=<0.002) however only biomechanically relevant for 90°. Russian tensioning is insufficient with a single wire, however the addition of an orthogonal wire increases tension in both wires, reaching the target range at 90° deflection. Further study using wire tensioners is warranted, and also the impact of non-orthogonal wire constructs.
The majority of 5th metatarsal fractures are successfully treated conservatively, with few patients requiring surgical fixation for symptomatic non-union. Tuberosity avulsion fractures are generally considered benign injuries with more distal fractures showing a propensity to develop delayed/non-union. We studied a cohort of patients who underwent surgery as treatment for non-union. We reported on outcome, rate of complications and requirement for additional surgery. All patients who required surgery to their 5th metatarsal from June 2008 to May 2018 were included. Demographic, clinical outcome data and radiographic classification of fracture types were collected, reviewed and analysed. 35 patients had undergone surgery for 5th metatarsal fractures during this time period and 31 of these had been operated on for a painful non-union. 12 were tuberosity avulsion fractures (Lawrence and Botte Type1) and 23 were Type 2/3. 5 patients (14.3%) experienced a further symptomatic non-union after initial surgery; Type 1 fractures were 11 times more likely to result in non-union (p=0.0375). 22.9% of the group required some form of further surgery, with a significant association between Type 1 fractures and the need for further surgery (p=0.0107). This study is the first of its kind, reporting specifically on the outcome after surgical fixation of a non-union of 5th metatarsal fractures. Overall, surgery had a good outcome with a low complication rate, though it is interesting to note that Type 1 fractures, which traditionally have a low non-union rate after conservative treatment, are associated with a significantly increased incidence of non-union if operated for symptomatic non-union.
The rising prevalence of osteoarthritis, associated with an ageing population, is expected to deliver increasing demand across Scotland for primary hip and knee arthroplasty in the future. Understanding the scale of potential change to operative workflow is essential to ensure adequate provision of services, and prevent prolonged waiting times that can cause patient harm. We therefore set out to provide projections of future primary hip and knee arthroplasty out to 2038 utilising historical trend data (2008–2018) from the Scottish Arthroplasty Project. All analyses were performed using the Holt's exponential smoothing projection method with the forecast package in R statistics. Results were adjusted for projected future population estimates provided by National Records of Scotland. Independent age & sex group predictions were also performed. All results are presented per 100,000 population at-risk per year (/100k/year). The predicted rise of primary hip arthroplasty for all ages is from 120/100k/year in 2018 to 152/100k/year in 2038, a 27% increase. The predicted rise of primary knee arthroplasty for all ages is from 164/100k/year in 2018 to 220/100k/year in 2038, a 34% increase. Based on a static 3 day length of stay average this would see 4280 additional patient bed days for hips, and 7392 for knees, required nationally per year by 2038. The associated supplementary cost to the NHS is anticipated to be around £21 million per annum. Knowledge of increasing resource utilisation and cost associated with predicted future demand for primary hip and knee arthroplasty provides key information for service organisation and delivery.
The aim of this study was to measure the effect of hospital case-volume on the survival of revision total knee arthroplasty (RTKA). A retrospective analysis of Scottish Arthroplasty Project data was performed. The primary outcome was RTKA survival at ten years. The primary explanatory variable was annual hospital case-volume. Kaplan-Meier survival curves were plotted with 95% confidence intervals (CI) to determine the lifespan of RTKA. Multivariable Cox proportional hazards were used to estimate relative revision risks over time. From 1998 to 2019, 8894 patients underwent RTKA surgery in Scotland (median age 70 years, median follow-up 6.2 years, 4789 (53.5%) females; 718 (8.8%) for infection). Of these patients, 957 (10.8%) underwent a second revision procedure on their knee. Male sex, younger age at index revision, and positive infection status were associated with need for re-revision. The ten-year survival estimate for RTKA was 87.3% (95%CI 86.5–88.1). Adjusting for gender, age, surgeon volume and infection status, increasing hospital case-volume was significantly associated with lower risk of re-revision (Hazard Ratio 0.78 (0.64–0.94, p<0.001)). The risk of re-revision steadily declined in centres performing >20 cases per year: relative risk reduction 16% with >20 cases; 22% with >30 cases; and 28% with >40 cases. The majority of RTKA in Scotland survive up to ten years. Increasing yearly hospital case-volume above 20 cases is independently associated with a significant risk reduction of re-revision. Development of high-volume tertiary centres may lead to an improvement in the overall survival of RTKA.
Debate surrounds the optimum operative treatment of periprosthetic distal femoral fractures (PDFFs) at the level of well fixed femoral components; lateral locking plate fixation (LLP-ORIF) or distal femoral replacement (DFR). To determine which attributed the least peri-operative morbidity and mortality we performed a retrospective cohort study of 60 consecutive unilateral PDFFs of Su types II (40/60) and III (20/60) in patients ≥60 years; 33 underwent LLP-ORIF and 27 underwent DFR. The primary outcome measure was reoperation. Secondary outcomes included perioperative complications and functional mobility status. Kaplan Meier survival analysis was performed. Cox multivariable regression analysis identified risk factors for reoperation after LLP-ORIF. Mean length of follow-up was 3.8 years (range 1.0–10.4). One-year mortality was 13% (8/60). Reoperation rate was significantly higher following LLP-ORIF: 7/33 vs 0/27, p=0.008. For the endpoint reoperation, five-year survival was better following DFR: 100% compared to 70.8% (51.8 to 89.8 95%CI) (p=0.006). For the endpoint mechanical failure (including radiographic loosening) there was no difference at 5 years: ORIF 74.5% (56.3 to 92.7); DFR 78.2% (52.3 to 100), p=0.182). Reoperation following LLP-ORIF was independently associated with medial comminution: HR 10.7 (1.45 to 79.5, p=0.020). Anatomic reduction was protective against reoperation: HR 0.11(0.013 to 0.96, p=0.046). When inadequately fixed fractures were excluded differences in survival were no longer significant: reoperation (p=0.156); mechanical failure (p=0.453). Reoperation rates are higher following LLP-ORIF of low PDFFs compared to DFR. Where adequate reduction, proximal fixation and augmentation of medial comminution is used there is no difference in survival between LLP-ORIF and DFR.
Sonographic callus may enable assessment of fracture healing. The aim of this study was to establish a reliable method for three-dimensional reconstruction of sonographic callus. Patients that underwent non-operative management of displaced midshaft clavicle fractures and intramedullary nailing of tibia fractures were prospectively recruited and followed to union. Ultrasound scanning was performed at periodical time points following injury. Infra-red tracking technology was used to map each image to a three-dimensional lattice. Criteria was fist established for two-dimensional bridging callus detection in a pilot study. Using echo intensity of the ultrasound image, semi-automated mapping was used to create an anatomic three-dimensional representation of fracture healing. Agreement on the presence of sonographic bridging callus was assessed using the kappa coefficient and intra-class-correlation (ICC) between observers. 112 clavicle fractures and 10 tibia fractures completed follow-up at six months. Sonographic bridging callus was detected in 62.5% (n=70/112) of the clavicles at six weeks post-injury. If present, union occurred in 98.6% of the fractures (n=69/70). If absent, nonunion developed in 40.5% of cases (n=17/42)(73.4%-sensitive and 100%-specific to predict union). Out of 10 tibia fractures, 7 had bridging callus of at least one cortex at 6 weeks and when present all united. Of the three patients lacking sonographic bridging callus, one went onto a nonunion (77.8%-sensitive and 100%-specific to predict union). The ICC for sonographic callus between four reviewers was 0.82 (95% CI 0.68–0.91) Three-dimensional ultrasound reconstruction of bridging callus has the potential to identify impaired fracture healing at an early stage in fracture management.
The aim was to determine the influence of COVID-19 on 30-day mortality in hip fracture. Secondary aims were to examine: (1) predictors of COVID-19 on presentation and later in the admission; (2) rate of hospital-acquired COVID-19; (3) predictive value of negative swabs on admission. A nationwide multicentre retrospective cohort study of all patients with hip fracture in all 17 Scottish hospitals in March-April. Demographics, blood results, COVID-19 status, Nottingham Hip Fracture Score (NHFS), management, length of stay (LOS), and 30-day mortality were recorded. 78/833 (9.4%) patients had COVID-19 (65 swab-proven). 30-day survival with COVID-19 was lower than without (65.4% vs 91%; p<0.001). COVID-19 within 7 days of admission (likely community-acquired) was independently associated with male sex (OR 2.34, p=0.040, CI 1.04–5.25) and COVID-19 symptoms (OR 15.56, CI 6.61–36.60, p<0.001). COVID-19 within 7–30 days (probable hospital-acquired) was independently associated with male sex (OR 1.73, CI 1.05–2.87, p=0.032), NHFS □7 (OR 1.91, CI 1.09–3.34, p=0.024), pulmonary disease (OR 1.68, CI 1.00–2.81, p=0.049), ASA □3 (OR 2.37, CI 1.13–4.97, p=0.022) and LOS □9 days (OR 1.98, CI 1.18–3.31, p=0.009). 38/65 (58.5%) of COVID-19 cases were probably hospital-acquired. The false negative rate of swabs on admission was 0% in asymptomatic and 2.9% in symptomatic patients. COVID-19 was associated with a threefold-increased 30-day mortality. Nosocomial transmission may have accounted for half of all cases. Identification of risk factors for having COVID-19 on admission, or acquiring COVID-19 later, may guide patient pathways. LOS was the only modifiable risk factor, emphasising the importance of high-quality, timely care.
The primary aim was to assess patient-reported outcomes following a humeral diaphyseal fracture. The secondary aim was to compare the outcomes of patients who achieved union after initial management (operative or non-operative) with those that achieved union after nonunion surgery. From 2008–2017, 291 patients (mean age 55yrs [17–86], 58% [n=168/291] female) were retrospectively identified and available to complete a survey. Sixty-four (22%) were managed with primary surgery and 227 (78%) non-operatively. Outcomes (QuickDASH, EQ-5D, EQ-VAS, SF-12) were obtained at a mean of 5.5yrs (1.2–11.0). After initial management, 229 patients (79%) united (n=62 operative, n=167 non-operative) and 62 (21%) developed a nonunion (n=2 operative, n=60 non-operative; p<0.001). Fifty-two of 56 patients (93%) achieved union after nonunion surgery. The overall mean QuickDASH was 20.8, EQ-5D 0.730, EQ-VAS 74, SF-12 PCS 44.8 and MCS 50.2. Patients who united after nonunion surgery reported a worse functional outcome (mean QuickDASH 27.9 vs. 17.6, p=0.003) and health-related quality of life (HRQoL; mean EQ-5D 0.639 vs. 0.766, p=0.008; EQ-VAS 66 vs. 76, p=0.036; SF-12 PCS 41.8 vs. 46.1, p=0.036) than those who united primarily. When adjusting for confounders, union after nonunion surgery was independently associated with poorer function (difference in QuickDASH 8.1, p=0.019) and HRQoL (difference in EQ-5D -0.102, p=0.028). Humeral diaphyseal union after nonunion surgery was associated with poorer function and HRQoL compared to patients who united primarily. Targeting early operative intervention to patients at risk of nonunion may have an important role, given the potential impact of nonunion on longer-term outcome.
Total ankle replacement (TAR) is performed for inflammatory arthropathy, osteoarthritis and other indications. The Scottish Arthroplasty Project (SAP) began collection of data on TAR in 1998. In this study, we look at trends in the use and outcomes of TAR in Scotland. We identified patients from the SAP who underwent TAR between 1998 and 2015 with imaging available on the National Picture Archiving and Communication System (PACS). We identified, and examined trends in implant type over the following time periods: 1998–2005; 2006–2010 and 2011–2015. Age, gender, indication, outcomes and trends in implants used for each time period were examined. There were 499 primary TAR procedures with an overall incidence of 0.5/105 population per year. Eight implants were identified with significant changes in the numbers of each type used over time. The peak incidence of TAR was in the 6th decade and mean age of patients increased from 59 years in 1998–2005, to 65 years in 2011–15 (p<0.0001). The percentage of patients with inflammatory arthropathy was 49% in 1998–2005, compared with 10% in 2011–2015. Arthrodesis and infection rates appeared to be higher during the first time period. The male to female ratio changed over time. The incidence of TAR increased overall during the study period (r= 0.9, p=<0.0001). This study examines a large number of TARs from an established arthroplasty registry. The rate of TAR has increased significantly in Scotland from 1998 to 2015. Indications and patient age have changed over time and could impact outcomes after ankle replacement.
The objective of this systematic review was to describe trapeziectomy outcomes and complications in the context of osteoarthritis of the base of the thumb after a five-year minimum follow-up. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to guide study design, and 267 full-text articles were assessed for eligibility. After exclusion criteria application, 22 studies were included, involving 728 patients and 823 trapeziectomies. Outcomes included pre- and postoperative clinical and radiological characteristics. Complications and revisions were recorded.Aims
Methods
Brachial plexus injury (BPI) is an often devastating injury that affects patients physically and emotionally. The vast majority of the published literature is based on surgeon-graded assessment of motor outcomes, but the patient experience after BPI is not well understood. Our aim was to better understand overall life satisfaction after BPI, with the goal of identifying areas that can be addressed in future delivery of care. We conducted semi-structured interviews with 15 BPI patients after initial nerve reconstruction. The interview guide was focused on the patient’s experience after BPI, beginning with the injury itself and extending beyond surgical reconstruction. Inductive and deductive thematic analysis was used according to standard qualitative methodology to better understand overall life satisfaction after BPI, contributors to life satisfaction, and opportunities for improvement.Aims
Methods
The aim of this study was to evaluate the need for hand trauma services during the COVID-19 pandemic lockdown, specifically related to surgical requirements. This will provide useful information for planning and resource allocation in the event of any further lockdown. A prospective analsysis of all patients attending our hand trauma unit throughout the UK COVID-19 lockdown period (24 March to 10 May 2020) was carried out. Prospectively collected departmental data from the same period in 2019 was obtained and reviewed for comparison. The number of patients attending clinic, undergoing surgery, the type of surgical procedure, and rate of surgery was compared.Aims
Methods
To assess the proportion of patients with distal radius fractures (DRFs) who were managed nonoperatively during the COVID-19 pandemic in accordance with the British Orthopaedic Association BOAST COVID-19 guidelines, who would have otherwise been considered for an operative intervention. We retrospectively reviewed the radiographs and clinical notes of all patients with DRFs managed nonoperatively, following the publication of the BOAST COVID-19 guidelines on the management of urgent trauma between 26 March and 18 May 2020. Radiological parameters including radial height, radial inclination, intra-articular step-off, and volar tilt from post-reduction or post-application of cast radiographs were measured. The assumption was that if one radiological parameter exceeds the acceptable criteria, the patient would have been considered for an operative intervention in pre-COVID times.Aims
Methods
We hypothesized that the wide-awake local anaesthesia with no tourniquet (WALANT) technique is cost-effective, easy to use, safe, and reproducible, with a low learning curve towards mastery, having a high patient satisfaction rate. Furthermore, WALANT would be a suitable alternative for the austere and developing nation environments where lack of funds and resources are a common issue. This was a randomized control trial of 169 patients who required surgery for closed isolated distal radius fractures. The study was performed between March 2016 and April 2019 at a public sector level 1 trauma centre. General anaesthesia was used in 56 patients, Bier’s block in 58 patients, and WALANT in 55 patients. Data were collected on pre-, peri-, and postoperative parameters, clinical outcome, hospital costs, and patient satisfaction. One-way analysis of variance (ANOVA) was used with a p-value of 0.05 being significant.Aims
Methods
The aim of the Scaphoid Magnetic Resonance Imaging in Trauma (SMaRT) trial was to evaluate the clinical and cost implications of using immediate MRI in the acute management of patients with a suspected fracture of the scaphoid with negative radiographs. Patients who presented to the emergency department (ED) with a suspected fracture of the scaphoid and negative radiographs were randomized to a control group, who did not undergo further imaging in the ED, or an intervention group, who had an MRI of the wrist as an additional test during the initial ED attendance. Most participants were male (52% control, 61% intervention), with a mean age of 36.2 years (18 to 73) in the control group and 38.2 years (20 to 71) in the intervention group. The primary outcome was total cost impact at three months post-recruitment. Secondary outcomes included total costs at six months, the assessment of clinical findings, diagnostic accuracy, and the participants’ self-reported level of satisfaction. Differences in cost were estimated using generalized linear models with gamma errors.Aims
